My invention `relates *toy al `'r{'eciprocatin'g.

trolley adapted .to .be operated uponl a kite string, orupon a supporting member posi'.-l

tioned lbetween fixed supports, andv having" sufficient `inclination to i cause the trolley to slide downwardly/by the forceol gravity,

after it has been-forced upwardly,I wind pressure, against wings mounted upon the trolley,

The obj ect ol? my Jinventioniis. to proyide autrolley whichfwillltravel back .andforth between two stops placedat any desi-red po-rv sitions upon the supporting .stringeor menuv ber; Ja iirtlfierl object oflmylinvention isto provide mechanism` upon the trolley for l holding; the wings in the operativeor inoperative position; a still .further Objectis to `pvroxfwide .double actingy shifting means adapted for changing the position of the Wings wheny the trolley. strikes a stop` in either: its upward or `doi'ivnwa'id l movement.

lVlien the trolley travels up the string and reaches the stop A, the forward end member 42 ot' thefshift bar 38'will strike against the' stop A, whichwill move the shift bar longitudinally in relation to the body 1 2 until'the pivot head 37 strikes the guard member 45 on the body 12, thus bringingthe links andthe wings` into the position'shown'in Figsf', 4 and in dotted lines Fig. 6.- IWhenv the wings are thus shifted i intov a 'positiony parallel lwith' the body 12 andthe string 20, as shown in Fig. 1, the wind will cease to act against the wings and thejweight or" the trolley will cause it to slide down Vthe string until it strikes the stopA B, ywhich-latter will re-setthe wings, into the position shown in Fig. 1, and in ful-l lines F ig. 6 sov that the wind will again torcetlief-tro'lley up'the string.` The shift bar 38 isv provided with a pin 48y upon which an article may be carried until y.theupper stop A shifts the parts into the position shown. in Fig. 4, when the pin 4S^willbe withdrawn from theguard member-'45 andthe bearing'member V40, which will force the articlevoii" the pin' 48 and cause it to fall vtromthe trolley. U The operation-"is as follows: The stop A may be placed at any point upon the string 20'; the trolley is placed upon the string by turning the string into the open spiral rings 42, 18, 19 and43. The trolley is supportedA by the rings 18 and 19`upon-the string; the wings/are set in the open position, as shown in Fig. -1v and full lines in Fig. 6; and the trolley released so'thatthe wind will force Ait up the string; the stop B is then placed upon the string, andthe trolley will travel back and forthupon the lstring between the lsteps- Ay and B. The wings will be autoinatically shifted into theinoperative position'byfthe impact ot the trolley against the stop A andthe wings ywill be automatically re-set Abyt-he impact or `the trolley against lthe stop B without any 'further attention from the operator. paid out until the stops A and B are far` The kite string may be the operator and thetrolley will conti'nue to travel back and forth between the stops.
